The normative turn in European Union studies: legitimacy, identity and democracy

By raising fundamental questions about the methods and ultimate goals of European integration, Maastricht forced supporters and opponents alike to confront the legitimacy both of the Union and - as has become apparent with the crisis of the Santer Commission - of the institutional architecture put in place to steer it. The strategic-oriented action and normative argument avoided for so long by the main political actors, are inescapable when tackling this issue. Thus, national politicians and European authorities have self-consciously, though perhaps confusedly, been obliged to start discussing the future shape of what Jacques Delors once called ‘un object politique non-identifié.’ Academics, for their part, have discovered that the integration process depends not simply on functional efficiency and certain given economic and national interests, but also on people’s ideals and perceptions. Consequently, explanation and justification have proved less easily distinguishable than earlier positivistic and behaviouralist models assumed. Hence, the ‘normative turn’ in European studies. In this essay we wish to clarify certain aspects of the normative turn (section 1) and to explore some of the substantive issues that emerge from subjecting the European integration process to normative scrutiny (sections 2, 3 and 4). In the conclusion, we shall sketch the kind of normative politics we feel best suits the emerging European polity

Hudson and Samson: The Roberts Court Confronts Privacy, Dignity, and the Fourth Amendment

This article critically analyzes Samson v. California and Hudson v. Michigan, which were the Roberts Court\u27s first major Fourth Amendment decisions. In Samson, the Court upheld a California law allowing government officials to search parolees without any suspicion of wrongdoing. In Hudson, to the surprise of almost every observer, the Court held that knock-and-announce violations do not carry with them a remedy of exclusion. What was most notable about Hudson was not only that it rejected what every state and every federal court, save one, believed to be the proper remedy for knock-and-announce violations, but that it called into question the Court\u27s continued support of a general Fourth Amendment exclusionary principle. In Part One, I examine the Court\u27s decision in Samson, tying it to a long line of cases dating back to the Burger Court that have segregated entire classes of individuals (and individuals in particular physical locations) from meaningful Fourth Amendment protection. While few would argue that Samson is a particularly groundbreaking decision, it is nonetheless notable as being the Roberts Court\u27s first major rights-limiting decision under the Fourth Amendment. I argue the majority\u27s reasoning is unconvincing, in that it depends on a misconceived notion of the criminal “propensity” of parolees that skews the Fourth Amendment “reasonableness” analysis. I argue that the Court\u27s abandonment of “special needs” doctrine in its decision provides evidence that the majority recognized the tenuous relationship between suspicionless searches and the penological and rehabilitative goals of parole. In Part Two, I examine the Court\u27s opening salvo against the exclusionary rule in Hudson. I critique Justice Scalia\u27s endorsement of alternative remedies to knock-and-announce violations (specifically his reliance on 42 U.S.C. §1983), arguing that these proposed remedies are inadequate to deter future misconduct and make whole the victims of the illegal behavior. Next, I assert that Hudson was the first shot across the bow in what promises to be a long campaign by the “conservative” block of the Court to undermine, and ultimately overrule, the exclusionary rule as a remedy for Fourth Amendment violations. In Part Three, I argue that the newly-composed Court\u27s decisions in these cases show a clear preference for the government\u27s interests in law enforcement, to the determinant of individuals\u27 legitimate expectations of privacy, dignity, and autonomy. Both Samson and Hudson offer tantalizing clues as to the new Roberts Court\u27s general theory of the balance of power between the state and the individual in the Fourth Amendment context; a theory which promises to carry over into the “new generation” of Fourth Amendment cases soon to come before the Court

Hyaline fibromatosis syndrome (juvenile hyaline fibromatosis): whole-body MR findings in two siblings with different subcutaneous nodules distribution

Abstract: Hyaline fibromatosis syndrome (juvenile hyaline fibromatosis) is a rare, progressive, autosomal recessive disorder whose main hallmark is the deposition of amorphous hyaline material in soft tissues, with an evolutionary course and health impairment. It may present involvement of subcutaneous or periskeletal soft tissue, or may develop as a visceral infiltration entity with poor prognosis. Very few radiological data about this inherited condition have been reported, due to the extreme rarity of disease. We herein present a case of two siblings, affected by different severity of the disease, with different clinical features. They were examined by whole-body MR (WBMR) in order to assess different lesions localization, to rule out any visceral involvement and any other associated anomalies and to define patients\ue2\u80\u99 management

L-Convex Polyominoes are Recognizable in Real Time by 2D Cellular Automata

A polyomino is said to be L-convex if any two of its cells are connected by a 4-connected inner path that changes direction at most once. The 2-dimensional language representing such polyominoes has been recently proved to be recognizable by tiling systems by S. Brocchi, A. Frosini, R. Pinzani and S. Rinaldi. In an attempt to compare recognition power of tiling systems and cellular automata, we have proved that this language can be recognized by 2-dimensional cellular automata working on the von Neumann neighborhood in real time. Although the construction uses a characterization of L-convex polyominoes that is similar to the one used for tiling systems, the real time constraint which has no equivalent in terms of tilings requires the use of techniques that are specific to cellular automata

New treatments for breast cancer: Breakthroughs for patient care or just steps in the right direction?

Three areas of clinical research in breast cancer treatment led to news breaking presentations at the American Society of Clinical Oncology (ASCO) meeting, 1998, in Los Angeles. All three subjects represent important advances in cancer medicine. Prevention: Two related drugs, tamoxifen and raloxifene, were found in placebo controlled trials to significantly reduce the incidence of breast cancer for women at increased risk of developing the disease. Patterns of relapse showed that the reduced rate of breast cancer was exclusively observed for tumors expressing estrogen receptors, while the rate of tumors classified as estrogen-receptor negative was similar for the treatment and the control groups. This may indicate that the observed reduction in breast cancer incidence is due to a treatment effect on occult disease rather than its prevention. We certainly have no adequate information on mortality prevention. Adjuvant therapies: Taxol given every three weeks for four courses following an adjuvant treatment with four courses of doxorubicin and cyclophosphamide (AC) combination was found to be superior to not adding treatment after the four courses of AC in a trial involving 3170 patients. At 22 months of median follow-up, the quoted P-values were P = 0.0077 for disease-free survival and P = 0.039 for overall survival, but these did not cross the prospectively defined interim analysis boundaries for statistical significance at the 0.05 level. The difference was observed early during follow-up, and was exclusively seen in the 40% of patients who had ER-negative primaries and, therefore, did not receive tamoxifen following chemotherapy. One may thus argue that the early difference observed was primarily due to differences in the duration of the treatment regimens in the two groups and the early entry into the trial of patients with particularly aggressive neoplasia (e.g., ER-negative primaries) who would have benefited from a longer duration treatment. Treatment of advanced disease: The use of monoclonal antibodies to c-erb-B2 was found to induce responses in metastatic breast cancer. Patients with tumors expressing c-erb-B2 responded to weekly infusions of this biological agent. It was particularly impressive that the response rate for patients receiving infusion of the monoclonal antibodies together with the cytotoxics was superior to that with chemotherapy alone in a randomized trial. It is important to note that only patients with tumors overexpressing c-erbB-2 (the overall incidence is about 20%) were tested. It must still be demonstrated that the effect of these monoclonal antibodies is indeed confined to cells overexpressing c-erbB-2. Treatment related cardiac tox-icity remains a problem, and the effects of treatment in various subsets of patients need to be defined before starting investigations in the adjuvant setting, which is a clear further objective of this specific research. The significant findings from clinical research opened several new questions, which must be answered before allowing them to be employed in routine patient car

Spectral properties of quantum NN-body systems versus chaotic properties of their mean field approximations

We present numerical evidence that in a system of interacting bosons there exists a correspondence between the spectral properties of the exact quantum Hamiltonian and the dynamical chaos of the associated mean field evolution. This correspondence, analogous to the usual quantum-classical correspondence, is related to the formal parallel between the second quantization of the mean field, which generates the exact dynamics of the quantum $N$-body system, and the first quantization of classical canonical coordinates. The limit of infinite density and the thermodynamic limit are then briefly discussed.Comment: 15 pages RevTeX, 11 postscript figures included with psfig, uuencoded gz-compressed .tar fil

Pyrazolium- versus imidazolium-based ionic liquids: Structure, dynamics and physicochemical properties

Ionic liquids (ILs) composed of two different pyrazolium cations with dicyanamide and bis(trifluoromethanesulfonyl)imide anions have been synthesized and characterized by NMR, Kamlet-Taft solvatochromic parameters, conductivity and rheological measurements, as well as ab initio calculations. Density functional calculations for the two pyrazolium cations, 1-butyl-2- methylpyrazolium [bmpz] and 1-butyl-2,3,5-trimethylpyrazolium [bm 3pz], provide a full picture of their conformational states. Homo- and heteronuclear NOE show aggregation motives sensitive to steric hindrance and the anions' nature. Self-diffusion coefficients D for the anion and the cation have been measured by pulsed field gradient spin-echo NMR (PGSE-NMR). The ionic diffusivity is influenced by their chemical structure and steric hindrance, giving the order Dcation > Danion for all of the examined compounds. The measured ion diffusion coefficients, viscosities, and ionic conductivity follow the Vogel-Fulcher-Tammann (VFT) equation for the temperature dependencies, and the best-fit parameters have been determined. Solvatochromic parameters indicate an increased ion association upon going from bis(trifluoromethanesulfonyl)imide to dicyanamide-based pyrazolium salts, as well as specific hydrogen bond donor capability of H atoms on the pyrazolium ring. All of these physical properties are compared to those of an analogous series of imidazolium-based ILs

On the terminal velocity of sedimenting particles in a flowing fluid

The influence of an underlying carrier flow on the terminal velocity of sedimenting particles is investigated both analytically and numerically. Our theoretical framework works for a general class of (laminar or turbulent) velocity fields and, by means of an ordinary perturbation expansion at small Stokes number, leads to closed partial differential equations (PDE) whose solutions contain all relevant information on the sedimentation process. The set of PDE's are solved by means of direct numerical simulations for a class of 2D cellular flows (static and time dependent) and the resulting phenomenology is analysed and discussed.Comment: 13 pages, 2 figures, submitted to JP

Adjuvant therapy after excision and radiation of isolated postmastectomy locoregional breast cancer recurrence: definitive results of a phase III randomized trial (SAKK 23/82) comparing tamoxifen with observation

Background: Adjuvant systemic treatment for patients with isolated locoregional recurrence (ILRR) of breast cancer is based on a single reported randomized trial. The trial, conducted by the Swiss Group for Clinical Cancer Research, compared tamoxifen (TAM) with observation after complete excision of the ILRR and proper radiotherapy. We performed a definitive analysis of treatment outcome at >11 years of follow-up, after the majority of the patients had a subsequent event of interest. Patient and methods One hundred and sixty-seven patients with ‘good-risk' characteristics of disease were randomized. ‘Good-risk' was defined as estrogen receptor expression in the ILRR, or having a disease-free interval of >12 months and a recurrence consisting of three or less tumor nodules, each ≤3 cm in diameter. Seventy-nine percent of the patients were postmenopausal at randomization. Results: The median follow-up time of the surviving patients was 11.6 years. The median post ILRR disease-free survival (DFS) was 6.5 years with TAM and 2.7 years with observation (P = 0.053). The difference was mainly due to reduction of further local relapses (P = 0.011). In postmenopausal patients, TAM led to an increase of DFS from 33% to 61% (P = 0.006). In premenopausal women, 5-year DFS was 60%, independent of TAM medication. For the whole study population, the median post-recurrence overall survival (OS) was 11.2 and 11.5 years in the observation and the TAM group, respectively; premenopausal patients experienced a 5-year OS of 90% for observation compared with 67% for TAM (P = 0.175), while the respective figures for postmenopausal patients were both 75%. Conclusions: These definitive results confirmed that TAM significantly improves the post-recurrence DFS of patients after local treatment for ILRR. This beneficial effect does not translate into a detectable OS advantag
